SUS mentions ‘VISUAL’ but without saying what it’s for: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html#tag_08 But <http://unix.stackexchange.com/questions/4859/visual-vs-editor-whats-the-difference> says something that seems to make sense, like what you wrote. I’ve committed a change that honors $VISUAL first, $EDITOR second. Thanks, Ludo’.
